Different electromagnetic energy sources that output differentwavelengths of light can be used together in performing variousprocedures. In the dental field, for example, different wavelengths oflight can be effective in performing various aspects of a dentalprocedure. In one system, electromagnetic radiation of a firstwavelength is applied in a teeth-whitening procedure (e.g., output froma laser or laser diode within a wavelength range of approximately 390nm-480 nm), and electromagnetic radiation of a second wavelength isapplied in a gum treatment procedure (e.g., output from a laser or laserdiode within a wavelength range of approximately 620 nm-680 nm). Theelectromagnetic radiation of the different wavelengths may be outputsimultaneously via a single device. A graphical user interface forcontrolling the plurality of electromagnetic energy sources used in thedevice may be desirable.

DETAILED DESCRIPTION

FIG. 1 depicts a block diagram of an example system 100 including agraphical user interface (GUI) 106 for controlling an electromagneticenergy source 102 having a plurality of laser sources 103. In the system100 of FIG. 1, the electromagnetic energy source 102 includes n separatelaser sources 103 (e.g., solid-state lasers, laser diodes) configured toproduce electromagnetic radiation at different wavelengths λ₁, λ₂, λ₃,λ₄, . . . λ_(n). The different wavelengths of the n laser sources 103may be utilized to perform a variety of different procedures (e.g.,simultaneous teeth-whitening and gum treatment in a dental procedure,where the teeth-whitening and the gum treatment procedures each utilizea different wavelength of light). The electromagnetic energy source 102is connected to both an electromagnetic radiation delivery system 104and a controller 108. The electromagnetic radiation delivery system 104routes the electromagnetic energy generated by the n sources 103 to atarget region 101. The electromagnetic radiation delivery system 104 maybe, for example, one or more multi-mode fiber optic cables configured toguide the output of the n laser sources 103. The electromagneticradiation delivery system 104 may also be an instrument (e.g., a medicalor dental instrument) configured to output the light of the n differentwavelengths. The target region 101 is an area to which theelectromagnetic energy generated by the n sources 103 is ultimatelydelivered and may be, for example, an area of the mouth (e.g., an areaincluding teeth and gums) or another area of a human body.

The controller 108 is connected to the electromagnetic energy source 102and is used to control the output of the n laser sources 103. Thecontroller 108 includes the GUI 106, which includes a total powercontroller 106A, on/off source toggle controllers 106B, andsingle-source controllers 106C. The total power controller 106A isconfigured to display and to allow a user to control a total outputpower of the n laser sources 103. The total output power of the n lasersources 103 is a combined output power determined by summing the outputpowers of each of the individual n laser sources 103. The total powercontroller 106A may be implemented on the GUI 106 via, for example, apie-graph, where the pie-graph includes a radius that indicates thetotal output power of the n laser sources 103. The total powercontroller 106A may allow a user to control the total output power as apercentage of a maximum total output power of the n laser sources 103.

The on/off source toggle controllers 106B and the single-sourcecontrollers 106C are each used to control the n laser sources 103individually. The on/off source toggle controllers 106B include aplurality of toggle buttons or switches, where the toggle button orswitch is configured to turn off or turn on a particular source of the nlaser sources 103. The single-source controllers 106C are eachconfigured to control the output power of a single one of the n lasersources 103. In one example, each of the plurality of the single-sourcecontrollers 106C is configured to control a percentage of the totaloutput power contributed by a single laser source of the n laser sources103. Each of the single-source controllers 106C may include, forexample, a slider control or a set of buttons that enables the user tocontrol the output power contributed by the single laser source of the nlaser sources 103.

An input from the user is received via the GUI 106, where the input isan interaction with the total power controller 106A, the on/off sourcetoggle controllers 106B, or the single-source controllers 106C. Based onthe input, a power output of one or more of the n laser sources 103 isadjusted. Thus, using various portions of the GUI 106, the user cancontrol the total (i.e., combined) output power of the n laser sources103, as well as the output power of each of the n sources 103individually. The electromagnetic energy source 102 may include avariety of different lasers, laser diodes, or other sources of light.The n sources 103 may include, for example, an erbium, chromium,yttrium, scandium, gallium garnet (Er, Cr:YSGG) solid state laser, whichgenerates light having a wavelength in a range of 2.70 to 2.80 μm. The nsources may also include an erbium, yttrium, aluminum garnet (Er:YAG)solid state laser; a chromium, thulium, erbium, yttrium, aluminum garnet(CTE:YAG) solid state laser; an erbium, yttrium orthoaluminate(Er:YAL03) solid state laser; a holmium, yttrium, aluminum garnet(Ho:YAG) solid state laser; a quadrupled neodymium, yttrium, aluminumgarnet (quadrupled Nd:YAG) solid state laser; an excimer laser; or acarbon dioxide (CO2) laser.

FIG. 2 depicts an example GUI 200 for controlling four electromagneticenergy sources. In the GUI 200 of FIG. 2, sectors of a pie-graph 202 andsingle-source controllers 209 are labeled 0, 1, 2, and 3, and each ofthe numbered sectors and single-source controllers correspond to one ofthe four electromagnetic energy sources. The pie-graph 202 is configuredto allow a user to control a combined, total output power of the fourelectromagnetic energy sources. A radius r 201 of the pie-graphindicates the total output power of the four electromagnetic energysources, such that the pie-graph 202 expands and shrinks as the totaloutput power increases and decreases, respectively. In the example ofFIG. 1, the total output power of the four electromagnetic energysources has a value of 100% of its maximum value, as indicated by a textbox 206 that is used to indicate the total output power. Because thetotal output power is at a maximum value, the radius r 201 of thepie-graph 202 is also at a maximum value.

The user can control the total output power of the four electromagneticenergy sources by changing the radius r 201 of the pie-graph 202. In oneexample, the radius r 201 of the pie-graph 202 is changed bydragging-and-dropping a point on a circumference of the pie-graph 202.In FIG. 2, because the total output power of the four electromagneticenergy sources is at the maximum value of 100%, the radius r 201 of thepie-graph 202 cannot be increased and can only be decreased to lower thetotal output power of the four electromagnetic energy sources. As notedabove, the GUI 200 of FIG. 2 includes the text box 206 that is used toindicate the total output power of the four electromagnetic energysources. The text box 206 of FIG. 2 displays a number that indicates thetotal output power of the four sources as a percentage of a maximumoutput power for the four sources. In another example, the text box 206displays a number that indicates the total output power of the foursources as an actual power value in watts.

The GUI 200 further includes total-power slider 204 including a handle203 that is configured to move along a predetermined path (i.e., asubstantially horizontal path in the example of FIG. 2). The user maymove the handle 203 of the total power slider 204 along thepredetermined path to control the total power output of the fourelectromagnetic energy sources. A position of the handle 203 along thepredetermined path of the total power slider 204 indicates the totaloutput power of the four sources. Thus, a user may control the totaloutput power of the four sources either by manipulating the radius r 201of the pie-graph 202 or by manipulating the handle 203 of thetotal-power slider 204. When the total output power is modified via thepie-graph 202 or via the total-power slider 204, other portions of theGUI 200 change correspondingly. For example, the number in the text box206 and the radius r 201 of the pie-graph 202 change in response to themoving of the handle 203 of the total-power slider 204, and the numberin the text box 206 and the position of the handle 203 of thetotal-power slider 204 change in response to the changing of the radiusr 201 of the pie-graph 202.

In one example, the position of the handle 203 or the radius r 201 ofthe pie-graph 202 change in a manner that is linear with respect to thechanges in the total output power, such that, for example, the radius r201 of the pie-graph 202 is 50% of its maximum length when the totaloutput power of the four electromagnetic energy sources is decreased to50% of its maximum value. In another example, the position of the handle203 or the radius r 201 of the pie-graph 202 change in a manner that isnot proportional to changes in the total output power of the foursources. In this example, the position of the handle 203 or the radius r201 of the pie-graph 202 may change according to a logarithmic scalewith respect to the changes in the total output power. For example,using a logarithm with base 10, if the maximum total output power is 40watts, and the total output power has been reduced to 5 watts (i.e.,12.5% of the maximum total output power), then log₁₀(40) isapproximately equal to 1.6, and log₁₀(5) is approximately equal to 0.7.If the radius r 201 is adjusted according to the logarithm with base 10,the radius r 201 at 5 watts will be 43% of the radius r 201 at 40 watts.

The pie-graph 202 includes a plurality of sectors (i.e., pie pieces)that indicate a percentage of the total output power contributed by eachof the four electromagnetic energy sources. In the example of FIG. 2,the sectors of the pie-graph 202 each have an angle of 90 degrees,indicating that each of the four electromagnetic energy sources iscontributing an equal amount of power (25%) to the combined total outputpower of the four sources. A particular, single source of the fourelectromagnetic energy sources is associated with a particular, singlesector of the pie-graph 202, such that the angle of the particularsector indicates the percentage of the total output power contributed bythe particular source. Using the GUI 200, the user is able to change theangle of a sector to change the percentage of the total output powercontributed by the particular source associated with the sector. In oneexample, the angle of a particular sector is changed bydragging-and-dropping a point on a partition between the particularsector and a sector adjacent to the particular sector. In anotherexample, the angle of the particular sector is changed bydragging-and-dropping a point within an area of the particular sector.

The GUI 200 of FIG. 2 also includes a plurality of the single-sourcecontrollers 209 that are each configured to allow the user to control apercentage of the total output power contributed by a particular source.Changing the percentage of the total output power contributed by theparticular source (i.e., via the sectors of the pie-graph 202 or via asingle-source controller 209) causes a change in a percentage of thetotal output power contributed by one or more of the other threeelectromagnetic energy sources. In one example, changing the percentageof the total output power contributed by the particular source changesan output power for a single other source of the four electromagneticenergy sources. For example, if the percentage of the total output powercontributed by source 0 is increased by 10%, the percentage of the totaloutput power contributed by source 1 may be decreased by 10%. In anotherexample, changing the percentage of the total output power contributedby the particular source changes an output power of the three otherelectromagnetic energy sources (i.e., all of the other sources). Forexample, if the percentage of the total output power contributed bysource 0 is increased by 9%, the percentage of the total output powercontributed by sources 1, 2, and 3 may each decrease by 3% (i.e., onethird of the increase in percentage of source 0).

Each of the plurality of the single-source controllers 209 includes asingle-source slider 208 with a handle 210 that is configured to movealong a predetermined path. The user may move the handle 210 along thepredetermined path to change the percentage of the total output powercontributed by the particular source associated with the slider 208. Aposition of the handle 210 along the predetermined path of thesingle-source slider 208 indicates the percentage of the total outputpower that is contributed by the particular source. The single-sourcecontroller 209 further includes a set of buttons 212. The set of buttons212 includes a first button that is configured to increase thepercentage of the total output power contributed by the particularsource when pressed and a second button that is configured to decreasethe percentage of the total output power contributed by the particularsource when pressed. In one example, the set of buttons 212 may be usedto perform fine adjustment of the percentage of the total output powercontributed by the particular source, while dragging-and-droppingportions of the pie-graph 202 or manipulating the single-source sliders208 may be used to perform coarse (i.e., rough) adjustment. The set ofbuttons 212 may adjust the percentage of the total output powercontributed by the particular source on a linear scale (i.e., eachbutton press adjusts the percentage by an equal amount) or may adjustthe percentage of the total output power in non-linear amounts (e.g., asequence of five button presses adjusts the percentage by 1%, 2%, 4%,8%, and 12%, respectively).

Each of the plurality of the single-source controllers 209 also includesa toggle button 213. The toggle button 213 is configured to turn off orturn on the particular source associated with the toggle button 213. Thesingle-source controller 209 also includes a text box 214, where thetext box 214 includes a number that indicates the percentage of thetotal output power contributed by the particular source. In the exampleof FIG. 2, because each of the four electromagnetic energy sources arecontributing an equal amount of power to the total, combined outputpower, each of the text boxes 214 indicates a value of 25%. A sum of thenumbers of the text boxes 214 is equal to 100. In another example, thetext box 214 does not display a percentage of the total output powercontributed by the particular source but rather indicates an actualoutput power of the particular source in watts.

In the example GUI 200 of FIG. 2, changing the total output power of thefour electromagnetic energy sources (i.e., by adjusting the radius r 201of the pie-graph 202 or by moving the handle 203 of the total-powerslider 204) changes an output power of each of the four electromagneticenergy sources. In one example, changing the total output power by aparticular percentage value causes a corresponding change in the outputpower of each of the four electromagnetic energy sources by theparticular percentage value. For example, if the total output power ofthe four electromagnetic energy sources is adjusted from 100% of themaximum total output power to 50%, the output power of each of the foursources would also be decreased by 50%. In this example, adjusting thetotal output power does not change the percentage of the total outputpower contributed by each of the four sources. Thus, in the example ofFIG. 2, each of the four sources would continue to contribute 25% of thetotal output power, notwithstanding the lowering of the total outputpower to 50% of its maximum value.

The GUI 200 may be used as part of the example system 100 of FIG. 1 andmay be used within the controller 108 to control the n laser sources 103of the electromagnetic energy source 102. Thus, although the example ofFIG. 2 illustrates use of the GUI 200 with four electromagnetic energysources, in other examples, the number of sources is greater than fouror less than four. The particular configuration of the GUI 200 depictedin FIG. 2 may represent a “default” setting for controlling a systemhaving four electromagnetic energy sources, where the total output poweris set at a maximum value of 100%, and each of the four sourcescontributes equally to the total output power. Other default settingswith non-equal percentages of the total output power contributed by thesources are used in other examples. Further, the GUI 200 may include anumber of preset programs that can be loaded from a memory. The presetprograms may be used to implement output powers of the fourelectromagnetic energy sources that are tailored for performing specificprocedures. For example, a preset program may be loaded in the GUI 200for performing a specific dental procedure. The specific dentalprocedure may use the different sources having the different wavelengthsto perform a variety of oral cleaning and disinfection actionssimultaneously. The variety of oral cleaning and disinfection actionsmay use, for example, laser light at wavelengths of 810 nm, 940 nm, and980 nm to perform teeth cleaning, teeth whitening, bacteria removal, gumtreatment, composite curing, or various other actions.

Other modifications may be made to the GUI 200 of FIG. 2. In one system,the single-source sliders 208 may be eliminated, such that only thebuttons 212 and the pie-graph 202 may be used to adjust the percentageof the total output power contributed by a particular source. In anotherexample system, up/down buttons that adjust the total output power ofthe four sources are included. Although the pie-graph 202 of FIG. 2 isdepicted as being circular in shape, in other examples, the pie-graph202 is of a variety of different shapes (e.g., oval, square, or anyother shape).

FIG. 3 depicts an example GUI 300 including a pie-graph 302 having aradius r₁ 301 that indicates a combined, total output power of fourelectromagnetic energy sources. In the example GUI 300 of FIG. 3, thecombined, total output power of the four electromagnetic energy sourceshas been decreased from 100% of a maximum total output power to 90% ofthe maximum total output power. This is indicated in a text box 306 thatis configured to indicate the total output power, where a number in thetext box indicates that the total output power is 90% of the maximumtotal output power of the four electromagnetic energy sources. Thedecreased total output power is also indicated in a total-power slider304, where a handle of the total-power slider 304 is moved from aright-most position of the slider 304 to another position 305 that isindicative of the total output power being 90% of the maximum totaloutput power.

The 90% total output power is also indicated by the radius r₁ 301 of thepie-graph 302. The radius r₁ 301 is smaller than a radius r₂ 303, wherethe radius r₂ 303 is the radius of the pie-graph 302 when the totaloutput power is set to 100% of the maximum total output power. The totaloutput power may have been adjusted in the example of FIG. 3 either bymoving the handle of the total-power slider 304 to its position 305(e.g., via a drag-and-drop procedure) or by changing the radius r₁ 301of the pie-graph 302 (e.g., by dragging-and-dropping a point on acircumference of the pie-graph 302).

In the example GUI 300 of FIG. 3, changing the total output power of thefour electromagnetic energy sources from 100% to 90% does not change apercentage of the total output power contributed by each of the foursources. A text box 313 included on a single-source controller for eachof the four electromagnetic energy sources indicates that each source iscontributing 25% of the total output power, and a position of a handleon each single-source slider 308 indicates the same. Although thepercentage of the total output power contributed by each of the fourelectromagnetic energy sources is not changed when the total outputpower is changed, an actual output power for each source changes.Changing the total output power by a particular percentage value causesa corresponding change in the actual output power of each of the fourelectromagnetic energy sources by the particular percentage value. Thus,in FIG. 3, adjusting the total output power from 100% to 90% causes eachof the four sources to output 90% of the power that the source wasoutputting when the total output power was at 100%. For example, if thetotal output power was 40 watts when the four sources were outputting100% of the maximum total output power, and each of the four sourceswere contributing 25% of the total output power (10 watts each), thenadjusting the total output power to 90% of the maximum total outputpower causes the total output power to drop to 36 watts, with eachsource continuing to contribute 25% of the total output power (9 wattseach).

FIG. 4 depicts an example GUI 400 with single-source controllers forfour electromagnetic energy sources, where changing a percentage of atotal output power contributed by a particular source causes acorresponding power change in a single other source. In the example GUI400 of FIG. 4, the total power output of the four electromagnetic energysources is at 90% of a maximum total output power for the four sources.This is indicated at a text box 406 indicating the total output power asa percentage of the maximum total output power for the four sources. Thetotal output power at 90% is also indicated in a total-power slider 404,which includes a handle having a position that indicates a total outputpower of 90% of the maximum total output power for the fourelectromagnetic energy sources. The total output power of 90% is furtherillustrated in a pie-graph 402 having a radius r₁ 401 that is less thana radius r₂ 405. The radius r₂ 405 is the radius of the pie-graph 402when the total output power is at 100% of the maximum total outputpower.

In the example GUI 400 of FIG. 4, four single-source controllers 420,440, 460, 480 are labeled 0, 1, 2, and 3, respectively. Each of the foursingle-source controllers 420, 440, 460, 480 is associated with aparticular source of the four electromagnetic energy sources and isconfigured to control the percentage of the total output powercontributed by the particular source. In the GUI 400, changing thepercentage of the total output power contributed by the particularsource by a particular percentage value causes a corresponding powerchange in a single other source. Specifically, the corresponding powerchange is a change of the particular percentage value, but of anopposite magnitude. Thus, in FIG. 4, the single source controller 420 isassociated with electromagnetic energy source 0, and a percentage of thetotal output power contributed by source 0 has been increased from 25%to 40%, as indicated at text box 419 and at single-source slider 407.The increase in the percentage of the total output power contributed bythe source 0 was implemented either by moving a handle of thesingle-source slider 407, by dragging-and-dropping a point on apartition 412 that separates sectors of the pie-graph 402, or by using aset of buttons of the single-source controller 420.

Changing the percentage of the total output power contributed by source0 causes the corresponding power change in electromagnetic energy source1, as indicated at single-source controller 440. In the single-sourcecontroller 440, a text box 417 indicates that a percentage of the totaloutput power contributed by the source 1 has decreased from 25% to 10%.The decrease of 15% is tied to the increase of 15% that occurred insource 0. The single-source controller 440 further indicates thecorresponding power change via a position of a handle of a single-sourceslider 408, which has been automatically adjusted downward to indicatethe decrease in 15% of the percentage of the total output powercontributed by source 1. Thus, adjusting the percentage of the totaloutput power contributed by the source 0 causes an automatic change inthe percentage of the total output power contributed by the source 1.

A percentage of the total output power contributed by sources 2 and 3are not affected by the adjustment to the percentage of the total outputpower contributed by source 0, as indicated at sliders 409, 411 and textboxes 413, 415 of single-source controllers 460, 480. A sum of thenumbers of the four text boxes 413, 415, 417, 419 for the single-sourcecontrollers 420, 440, 460, 480 is equal to 100. Although the example ofFIG. 4 illustrates that adjusting the percentage of the total outputpower contributed by a particular source causes a corresponding powerchange in a single other source of the four electromagnetic energysources, in other examples, multiple other sources are affected byadjusting the power contributed by the particular source. For example,in other GUI systems, changing the percentage of the total output powercontributed by the source 0 causes a change of a percentage of the totaloutput power contributed by each of the other three sources of theplurality of the electromagnetic energy sources. Thus, if the percentageof the total output power contributed by source 0 was increased by 15%,as in the example of FIG. 4, the percentage of the total output powercontributed by sources 1, 2, and 3 would each be decreased by an equalamount, 5% (i.e., the increase of 15% that occurred in source 0 dividedby the number of other sources).

FIG. 5 depicts an example GUI 500 and illustrates an effect of changinga percentage of a total output power contributed by a singleelectromagnetic energy source. In the example GUI 500 of FIG. 5, foursingle-source controllers 520, 540, 560, 580 are labeled 0, 1, 2, and 3,respectively, and are associated with electromagnetic energy sourceshaving these number designations. In the example of FIG. 5, the singlesource controller 540 corresponds to electromagnetic energy source 1,and a percentage of the total output power contributed by source 1 hasbeen increased from 10% to 20%, as indicated at text box 517 andsingle-source slider 508. The increase in the percentage of the totaloutput power contributed by the source 1 was implemented either bymoving a handle of the single-source slider 508, bydragging-and-dropping a point on a partition 512 that separates sectorsof the pie-graph 502, or by using a set of buttons of the single-sourcecontroller 540.

Changing the percentage of the total output power contributed by source1 causes a corresponding power change in electromagnetic energy source2, as indicated at single-source controller 560. In the single-sourcecontroller 560, a text box 515 indicates that a percentage of the totaloutput power contributed by the source 2 has decreased from 25% to 15%.The drop of 10% corresponds to the increase of 10% that occurred insource 1. The single-source controller 560 further indicates thecorresponding power change via a position of a handle of a single-sourceslider 509, which has been automatically adjusted downward to indicatethe decrease in 10% of the percentage of the total output powercontributed by source 2. A percentage of the total output powercontributed by sources 3 and 0 are not affected by the adjustment to thepercentage of the total output power contributed by source 1, asindicated at sliders 507, 511 and text boxes 513, 519 of single-sourcecontrollers 520, 580.

FIG. 6 depicts another example GUI 600 and illustrates an effect ofchanging a percentage of a total output power contributed by a singlesource. In the example GUI 600 of FIG. 6, four single-source controllers620, 640, 660, 680 are labeled 0, 1, 2, and 3, respectively, and areassociated with electromagnetic energy sources having these numberdesignations. In the example of FIG. 6, the single source controller 660corresponds to electromagnetic energy source 2, and a percentage of thetotal output power contributed by source 2 has been increased from 15%to 25%, as indicated at text box 615 and single-source slider 609. Theincrease in the percentage of the total output power contributed by thesource 2 was implemented either by moving a handle of the single-sourceslider 609, by dragging-and-dropping a point on a partition 612 thatseparates sectors of pie-graph 602, or by using a set of buttons of thesingle-source controller 660.

Changing the percentage of the total output power contributed by source2 causes a corresponding power change in electromagnetic energy source3, as indicated at single-source controller 680. In the single-sourcecontroller 680, a text box 613 indicates that a percentage of the totaloutput power contributed by the source 3 has decreased from 25% to 15%.The drop of 10% corresponds to the increase of 10% that occurred insource 2. The single-source controller 680 further indicates thecorresponding power change via a position of a handle of a single-sourceslider 611, which has been automatically adjusted downward to indicatethe decrease in 10% of the percentage of the total output powercontributed by source 3. A percentage of the total output powercontributed by sources 0 and 1 are not affected by the adjustment to thepercentage of the total output power contributed by source 2, asindicated at sliders 607, 608 and text boxes 617, 619 of single-sourcecontrollers 620, 640.

The GUIs 400, 500, 600 of FIGS. 4-6 illustrate example systems where theelectromagnetic energy sources are connected conceptually in a“clockwise” arrangement, such that an adjustment to the percentage ofthe total output power contributed by a particular source only causes achange in output power for a single other source that is adjacent to theparticular source in a clockwise direction. Thus, if the electromagneticenergy sources are numbered 0, 1, 2, and 3, as in FIGS. 4-6, a powerchange in source 0 affects only a power output of source 1, a powerchange in source 1 affects only a power output of source 2, a powerchange in source 2 affects only a power output of source 3, and a powerchange in source 3 affects only a power output of source 0.

FIG. 7 depicts an example GUI 700 and illustrates use of a toggle button703 to disable one of four electromagnetic energy sources. A totaloutput power for the four electromagnetic energy sources is set at 100%of a maximum total output power, as indicated by text box 706,total-power slider 705, and a radius of a pie-graph 702 that is at amaximum value. In the example GUI 700 of FIG. 7, four single-sourcecontrollers 720, 740, 760, 780 are labeled 0, 1, 2, and 3, respectively,and are associated with electromagnetic energy sources having thesenumber designations. As indicated at the single-source controller 760,source 2 has been disabled via the toggle button 703, which isconfigured to turn the source off or on when pressed, depending on thecurrent state of the source. The disabled state of source 2 is indicatedat a text box 717 and via a position of a handle on a single-sourceslider 709. Further, the disabled state of source 2 is also indicated atthe pie-graph 702, which does not include a sector corresponding to thesource 2. In an example system, a source may only be disabled bypressing a toggle button, as in FIG. 7. In this example, using sliders707, 708, 709, 711 or up/down arrow buttons of the single-sourcecontrollers 720, 740, 760, 780 can be used to decrease the percentage ofthe total output power to a minimum value (e.g., 1%), but the sliders orthe up/down arrow buttons cannot be used to eliminate all output from asource.

Disabling source 2 via the toggle button 703 causes a correspondingpower change in source 3, as indicated at single-source controller 780.At the single-source controller 780, a text box 713 indicates thatsource 3 is now contributing 50% of the total output power of the foursources. Because source 2 was contributing 25% of the total output powerprior to being disabled, the 25% decrease in the output powercontributed by the source 2 causes a 25% increase in the total outputpower contributed by the source 3. The increased contribution of thesource 3 is also indicated via a position of a handle of a single-sourceslider 711. In the example of FIG. 7, changing the percentage of theoutput power contributed by a particular source affects only thepercentage of the output power contributed by a single other source,such that a percentage of the total output power contributed by sources0 and 1 are not changed, as indicated at the single-source controllers720, 740. At the single-source controllers 720, 740, sliders 707, 708and text boxes 716, 719 indicate that the sources 0 and 1 continue tocontribute 25% of the total output power and are not affected by thedisabling of source 2.

FIG. 8 depicts an example GUI 800 illustrating two activeelectromagnetic energy sources and two disabled electromagnetic energysources. In the example GUI 800 of FIG. 8, four single-sourcecontrollers 820, 840, 860, 880 are labeled 0, 1, 2, and 3, respectively,and are associated with electromagnetic energy sources having thesenumber designations. As indicated at the single-source controllers 860and 840, sources 1 and 2 have been disabled via toggle buttons 803, 805.The disabled state of sources 1 and 2 are indicated at text boxes 816,817 and via positions of handles of single-source sliders 808, 809. Apie-graph 802 also illustrates that sources 1 and 2 are disabled andincludes sectors corresponding to sources 0 and 3 only.

FIG. 9 depicts an example GUI 900 illustrating single-laser operation.In the example GUI 900 of FIG. 9, four single-source controllers 920,940, 960, 980 are labeled 0, 1, 2, and 3, respectively, and areassociated with electromagnetic energy sources having these numberdesignations. As indicated at the single-source controllers 940, 960,980, sources 1, 2, and 3 have been disabled via toggle buttons 903, 904,905. The disabled state of sources 1, 2, and 3 are indicated at textboxes 916, 917, 918 and via positions of handles of single-sourcesliders 908, 909, 910. A pie-graph 902 also illustrates that sources 1,2, and 3 are disabled and includes only a sector corresponding to source0. In this example, only the total output power for the four sources canbe adjusted. In the single-source controller 920 for source 0, asingle-source slider 907 and up/down buttons 906 are disabled, such thata percentage of the total output power contributed by the source 0cannot be adjusted. Rather, only a handle of a total-power slider 932can be adjusted to change the total output power, which changes theoutput power of the single source that is active, source 0.

FIG. 10 illustrates methods of manipulating a sector of a pie-graph tochange a percentage of a total output power contributed by a particularsource. As explained above with respect to the preceding figures, apie-graph portion of a GUI may include a plurality of sectors (i.e., piepieces) that indicate a percentage of the total output power contributedby each of the plurality of the electromagnetic energy sources. Thus, aparticular electromagnetic energy source is associated with a particularsector of the pie-graph, with the particular sector having an angle thatindicates the percentage of the total output power contributed by theparticular source. Changing the angle modifies the percentage of thetotal output power contributed by the particular source.

In a pie-graph 1000 of FIG. 10, an angle of a sector 1002 is changed bydragging-and-dropping a point 1004 on a partition between the sector1002 and an adjacent sector. In a pie-graph 1020, an angle of a sector1022 is changed by dragging-and-dropping a point 1024 within an area ofthe sector 1022. Changing the angle of the sector 1022 in this mannerdoes not involve manipulating any part of the partition 1026 between thesectors. In a pie-graph 1040, a resize box 1044 is used to change anangle of a sector 1042. The resize box 1044 may be located at aperimeter area of the pie-graph 1040, and a drag-and-drop action may beperformed at the resize box 1044 to change the angle of the sector 1042.

FIG. 11 depicts an example GUI 1100 where single-source controllers havebeen eliminated, and a single slider 1102 and a set of buttons 1104 areused to adjust an output of four electromagnetic energy sources. The GUI1100 of FIG. 11 includes a pie-graph 1106 configured to control a totaloutput power of the four electromagnetic energy sources. The pie-graph1106 includes a radius that indicates the total power output of the foursources and a plurality of sectors that indicate a percentage of thetotal output power contributed by each of the four electromagneticenergy sources. Rather than include a plurality of single-sourcecontrollers (e.g., including sliders and buttons configured to control apercentage of the total output power contributed by a particular sourceof the four electromagnetic energy sources), the example of FIG. 11includes the single slider 1102 and the set of buttons 1104. When onebutton of the set of buttons 1104 is pressed, the slider 1102 can beused to adjust the percentage of the total output power contributed by aparticular source associated with the pressed button. For example, toadjust the percentage of the total output power contributed by a source0, a button numbered 0 is pressed, and the slider 1102 can then be usedto adjust the output power of source 0. When no buttons are depressed,the slider 1102 can be used to adjust the combined, total output powerof the four sources.

FIG. 12 depicts an example GUI 1200 including a pie-graph 1202 with aplurality of sectors 1204, where a radius 1206 of a sector indicates anoutput power of a particular electromagnetic energy source. In precedingfigures, an angle of a sector of a pie-graph indicated power output of aparticular source. In FIG. 12, by contrast, the radius 1206 of thesector is used to indicate this. FIG. 12 also differs from precedingfigures in that text boxes 1208 are used to indicate an actual outputpower of a particular source, rather than a percentage of the totaloutput power for the particular source. In the example of FIG. 12, eachof the sources have a maximum output power of 20 watts, and numbers inthe text boxes 1208 indicate the actual output power of each of thesources in watts. Although no total-power slider or text box indicatingthe total output power is included in the example of FIG. 12, in otherexamples, the total-power slider or the text box may be included toallow display or adjustment of the total output power.

FIG. 13 depicts another example GUI 1300 including a pie-graph 1302 witha plurality of sectors 1304, where a radius 1306 of a sector indicatesoutput power of a particular electromagnetic energy source. As in FIG.12, the radius 1306 of the sector is used to indicate output power of aparticular electromagnetic energy source, and text boxes 1308 are usedto indicate an actual output power of the particular source in watts. Inthe GUI 1300 of FIG. 13, source 1 has been disabled, and source 0 hasbeen set to output a maximum output power of 20 watts. These adjustmentswere made either by adjusting handles of slide bars 1310, bymanipulating sectors 1304 of the pie-graph 1302 (e.g., bydragging-and-dropping a portion of a sector in a radial direction tomodify the radius 1306 of the sector), or by pressing up/down buttons1312.

FIG. 14 is a flowchart illustrating a method for controlling a pluralityof electromagnetic energy sources. At 1402, instructions are executed ona processor to display on a computer-human interface display device auser interface region. The user interface region includes a pie-graphconfigured to display a total output power of the plurality of theelectromagnetic energy sources. The pie-graph includes a radius thatindicates the total output power and a plurality of sectors that areconfigured to indicate percentages of the total output power contributedby each of the plurality of the electromagnetic energy sources. At 1404,an input is received via the user interface region, where the input isan interaction with the pie-graph that changes one of the radius or asector of the plurality of the sectors. At 1406, a power output of oneor more of the electromagnetic energy sources is adjusted based on theinput.
